What is Lemongrass?
Lemongrass, grown in Asia, Australia, and Africa, encompasses a variety of plants in the grass family. Some of those varieties are used as herbs in both culinary and medicinal applications. Flavor: Bright, citrus Often found in: Southeast Asian dishes, like beef rendang or tom yum soup Substitutes: 2 stalks of lemongrass = zest of 1 lemon. Not an ideal substitute, but will work in a pinch! Lemongrass can grow to several feet; it is tall and stalky with a vibrant green hue. Across the globe, the herb is cultivated for its strong aroma and bright, citrus flavors. Lemongrass is a critical ingredient in many Southeast Asian dishes, such as beef rendang or tom yum soup. You can find it in salad dressings, curry pastes, and marinades. In parts of India, lemongrass finds its way into masala chai, rice, and meat dishes. Bintu Hardy, a food blogger and recipe developer, details her experiences growing up drinking a refreshing ginger and lemongrass iced tea in Sierra Leone.
Dried vs. Fresh Lemongrass
There are two types of dried lemongrass:
Dried and cut stalks of lemongrass: Compared to fresh lemongrass, dried lemongrass has an earthier flavor with less brightness. But it does retain some of the complexity of the fresh variety, and it is a solid option for simmering in soups and curries. Cook’s Illustrated recommends against cooking with dried lemongrass in stir-fry (or drier dishes), as the texture is less favorable. Dried lemongrass stalks ground into a powder: Ground lemongrass or lemongrass powder is ideal for soup, curry, or stir-fry. Start with just a pinch, as the ground form is quite potent.
If you are able to source fresh lemongrass, I highly recommend it over the dried versions to be able to taste the full complexity of the herb. I often purchase lemongrass in bulk and store it in the freezer when needed.
Where to Buy Lemongrass
You can find fresh lemongrass in specialty Asian grocery stores and certain larger grocery stores, such as Whole Foods. Dried lemongrass can be purchased at specialty spice shops, in-person or online. Curio Spice and The Spice House are two reputable shops with high-quality spices. When buying lemongrass, look for stalks with a strong aroma and a green hue. Avoid selecting stalks that appear dried out or brown.
Lemongrass vs. Lemons
Though lemongrass and lemons have similar aromas, they are two very different ingredients. Lemongrass is more complex in scent and flavor, with slight woody, spicy notes.
Lemongrass Substitutes
Because lemongrass boasts a robust set of flavors, there isn’t a perfect substitute. In a pinch, though, there are a couple of options:
Lemon zest: 2 stalks of lemongrass = zest of 1 lemonDried lemongrass: 1 stalk of lemongrass = 1 teaspoon dried lemongrass
The resulting dish won’t have the same flavor profile, but these substitutes are quick and easy.
How to Prep Lemongrass
Lemongrass is woody, stiff, and fibrous and needs some prep before you can use it in cooking. From here, you can prep as needed for your particular recipe. For example, lemongrass can be sliced into thin rings for a stir-fry, ground into a paste for a curry, or simmered whole for a stew. Refrigerated stalks of lemongrass, wrapped in plastic wrap, should stay fresh for about two weeks.
How to Freeze Lemongrass
Wrap the trimmed and peeled lemongrass stalks in plastic wrap and place into a freezer-safe, airtight container or plastic bag. Store in the freezer for 3 to 4 months.
